What is the value of x

Mathematics
1 answer:

X=3



Explanation:

A straight line equals 180°, and they give you the one angle of 56°, so you know 56+ the other equation has to equal 180

56+4x+112=180
168+4x=180

Subtract 168 from both sides

4x=12

Divide 4 from both sides

X=3


You can check by filling it in.


56+4*3+112=

12+56+112=180

AnnyKZ [126]

Answer:

3000 words

Step-by-step explanation:

450 words in 3 minutes is 150 words in 1 minute. 20 minutes = 1 times 20.          

1 minute = 150 words so 150 words times 20 minutes = 3000 words.

Which graph represents the function f(x) = |x + 3|?
DIA [1.3K]

Answer:

Graph of Modulus

The graph of a modulus or absolute value function is in a form of a 'V' shape whose vertex depends upon the coordinates. The equation for the graph is given as,

where,

(a, b) are the coordinates of the vertex of 'v' in the form of (x, y),

And h shows how wider or lean will be the function, for h=0, it is a straight line, while for a negative value the graph will face downwards and opposite for a positive value.

Given to us

y = |x-3|

On the coordinate plane

The graph will be in the shape of a 'V' whose vertex will lay at the coordinates (3, 0). As the value of a is 1 the graph will face upwards. As shown below on the graph.

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2 1 inches. She p
Sauron [17]

The expression used for the length of ribbon that she needs for both pillows will be 4(2x^{2} +4x-6).

The total length of the pillow she needs will be  130 inches.

Given,

The side length of pillow is (2x^2 + 1) \ inches.

The side length of another pillow is 4x-7 \ inches.

We know that perimeter of square will be,

P=4\times length

So the perimeter of pillow will be,

P=4\times (2x^2+1)\\

P=8x^{2} +4

Similarly, the perimeter of another pillow will be,

P=4\times (4x-7)]

P=16x-28

Hence,the total length of ribbon that she needs for both the pillows will be,

8x^{2} +4+16x-28\\8x^{2} +16x-24\\4(2x^{2} +4x-6)

If x=3.5\\ then the total length of ribbon will be,

4(2\times 3.5^{2}+4\times 3.5-6)\\4(2\times 12.25+14-6)\\

4(24.5+8)

4\times 32.5\\

130 \ inches.

Thus the required expression will be 4(2x^{2} +4x-6) and the total length of ribbon she needs will be 130 inches.

So, the correct option will be (D).
